Weather Station values incorrect - retrospective correction

[mikechristelow]

Hi All,

I discovered today that my weather station (Technoline WS2350) has been under-recording the barometric pressure by about 20hPa i.e. the station was showing 993.5 but the actual was 1013.5hPa (based on other local weather data).

I beleive this occurred a couple of months ago when there was a power failure and my UPS backup was exhausted before the supply was restored. I suspect I forgot to correctly set the current hPa value on the station on restarting, so it has been wrong ever since.

To overcome this in Cumulus data, can I simply overwrite the Minimum and Maximim Pressure values in the dayfile.txt file with the recorded values + 20, for all the dates since the date of the power failure?

Many thanks,
Mike C

That is what I would've done.

And I suppose you ought to do the same for everywhere else that pressure values are stored (e.g. the monthly logs).
